Production process for photovoltaic cable with high electric conductivity

Abstract

The invention discloses a production process for a photovoltaic cable with high electric conductivity. The production process comprises conductor core processing, insulating layer processing, packaging, cooling, character printing and forming a cable, and package examining. Particularly, the production process comprises the following steps: (a) conductor core processing: preparing a multilayer conductor core through intertwisting by a wire twisting machine; (b) insulating layer processing: forming an insulating layer through high-temperature extruding and flowing out of a fluorine adding mold port; (c) protecting layer processing: mixing polytetrafluoroethene with extrusion assisting agent, preparing a product after procedures such as extrusion, (d) packaging: packaging the conductor core by the insulating layer; (e) cooling: cooling the insulating layer, and extruding the protecting layer on the insulating layer; (f) character printing and forming the cable: printing characters on the surfaces of wires, and preparing the cable through the wires; and (g) package examining: performing quality examining on the cable, and warehousing the packaged products. The solar photovoltaic cable prepared according to the method of the invention has advantages of excellent corrosion resistance, high oil resistance, high strong-acid and strong-base resistance, and high oxidation resistance. Furthermore the specific intertwisted structure of the conductor core realizes more stable use performance and longer service life of the cable.

Description

【Technical field】 [0001] The invention relates to the technical field of cable manufacturing, in particular to the technical field of a production process of a photovoltaic cable with high conductive efficiency. 【Background technique】 [0002] Solar energy technology will become one of the green energy technologies in the future. Solar energy or photovoltaics are widely used in China. In addition to the rapid development of government-supported photovoltaic power plants, private investors are also actively building factories and plan to put into production solar modules for global sales. . The performance of a photovoltaic power generation system not only depends on the efficiency or performance of the solar module itself, but also requires many components that do not seem to be directly related to the module, such as junction boxes, inverters, and photovoltaic cables. Among them, the photovoltaic cable is also one of the important factors that affect the service life of th...

Problems solved by technology

The equipment needs to withstand harsh weather conditions and mechanical shocks. Photovoltaic cables have high requirements for the softness, conductivity and flame retardancy of the cables. Most of the existing photovoltaic cables cannot meet the requirements of the application. Short, easy to age, frequent replacement increases the cost of use, therefore, it is necessary to further improve the material selection and process of photovoltaic cables
